Thisinvention relates to lateral motion de: vices for locomotives, and more, particularly tosuch-devioes in their applicationto trailingtrucks,,suchfor instance as the four Such trucks are to support the back end ofalocomotive with the capacity forsupporting a booster;motor vor analogous device h h nsua1 manner, iii-desired. The in creased carrying capacity. of the four wheel truck overthatoij' a two wheel truckis atltained, by virtue of the additional axleand pair ofwheels and the increase in friction",

between the wheel flanges and the rails when thetruck' passes over curved-track maybe substantially decreased by affording one of theaxles and its wheels a limited amount of lateral motion. A truck of this character has been described and claimed in US. Re

In the manner; generally known in the art, the inner end'of thej ournalbioxis left open toreeeive the; journal 1, and is formed with rifiang -i -i A grocoiveb is ,iformed in: the outer sideaof .thefiange in which isimounted a wearl g ace fiyt in t ble bearing metal, for the hub face 7 ofaa; wl1ecl mountdontheaxle, An inwardly p 'ojeQtiIIg'flange-S is spaced fromtheinnjer-side-of the flangev 4 providing" agrove 9 around-thesides of'gthe journal box, in w ic cgroovea dust guard 10, is'held. The dust guard 10, surrounds the axlejournal and; acts to protect the interior of" the box from dust onioreign matter. A wedge 11 is dispo edxheneath theupper side vof-the journal o -a d?alongi udilial groove 12'is formed along the bottorn offthesame. A bearing 13 of 'suitablematerial such; as, brass or bronze, and {provided with an upwardly extending flange on itsinneRend, is disposed above the axle journal, its upper part being wedge shaped and engaging the groove 12, ofthe edge. Thebearing l3 is held against inward lateral :motion inethe usual manner by,

the jOurnal box. Theflange', on the inner end oi ,thmbearing 13, and. a. lug projecting from the upper journal box wall serve to hold the wedgell in lateral position and to permit its removal from the box when the latter is raised,-the flangeon the inner end of the I outward movement.

The ends of the arms 18 are secured to flanges 19 formed on the journal box, by the bolts 20. Aplunger .21 isdisposedin the sleeve 17, so that a head 22, on its inner end, is position'ed adjacent the end of the journalwl.

A spring 23 is mounted aroundgthe sleeve 17, its outer end bearing ona flange 24 formed integrally with the sleeve, and its inner end bearing on a washer 25 "disposed on -"the plunger 21 at the inner side ot its; head;;22

The lower portion of' the wallisprovided with a .501. a I asaforedescribed, upon passing over a curved shown'inJFigP3, the castle nut will restrict itirom any inward-movement therefrom and will also serve to hold the plunger againstthespring'at a suitable normal tension; 'A casing 27 ismounted on the sleeve 17', sur rounding thespring 23, the casing being" rigidly secured to said :sleeve bysuitable port 29, in which a removable plug- 30 is fittedto permit the drainingof the journal boxgof oil or the cleaning 'of the-same.

' or the truck willbe permitted to move a'pre- I determined distance,- as indicated by" the space'between the wearing face 6 on the box and the hub face 7, this distance being sufficient to'allo'w the'wheels to pass over the* curved" track while substantially decreasing the friction caused thereby between their; flanges and the railsl Upon" such" lateral movement "the plunger 21' whichisdisposed in the journal box on that side of the truck towarcbwhich the axle is laterally'moved,

will be forced outward by the end of the -:axl'e1 against the tension'of the spring 23, the

plunger being free however,for such revolv= ing motion as the journal will tend to trans-1 mit thereto.
